Question 80
Q. How does the Lord's Supper differ from the Roman Catholic Mass?
A. The Lord's Supper declares to us that all our sins are completely forgiven through the one sacrifice of Jesus Christ, which he himself accomplished on the cross once for all. It also declares to us that the Holy Spirit grafts us into Christ, who with his true body is now in heaven at the right hand of the Father where he wants us to worship him. But the Mass teaches that the living and the dead do not have their sins forgiven through the suffering of Christ unless Christ is still offered for them daily by the priests. It also teaches that Christ is bodily present under the form of bread and wine where Christ is therefore to be worshiped. Thus the Mass is basically nothing but a denial of the one sacrifice and suffering of Jesus Christ and a condemnable idolatry.
Scripture proofs
John 19:30; Heb. 7:27; 9:12, 25–26; 10:10–18.
John 19:30 Therefore when Jesus took the sour wine, He said, “It has been finished.” And having bowed the head, He yielded up the spirit.
Heb. 7:27 who has no need every day, as the first high priests, to offer up sacrifices for [his] own sins, then for those of the people; for He did this once for all, having offered up Himself.
9:12, 25–26 12 nor by blood of goats and calves, but through [His] own blood, He entered once for all into the holy [places], having obtained eternal redemption. 25 nor that He should offer Himself many times, just as the high priest enters into the holy [places] every year with the blood of another. 26 Otherwise it was necessary for Him to have suffered many times from the foundation of the world. But now He has been revealed once in the consummation of the ages for the putting away of sin by the sacrifice of Himself.
10:10–18 10 in which act of will, we are having been sanctified through the offering of the body of Jesus Christ once for all. 11 And indeed every priest has stood every day, serving and offering the same sacrifices many times, which never are able to take away sins. 12 But this One, having offered one sacrifice for sins unto perpetuity, sat down at the right hand of God, 13 [as to] the rest awaiting until His enemies should be placed [as] a footstool for His feet. 14 For by one offering, He has perfected unto perpetuity those being sanctified. 15 And the Holy Spirit also testifies to us. For after having said: 16 “This [is] the covenant that I will make with them after those days, says the Lord, giving My laws on their hearts, and I will inscribe them on their mind,” 17 then [He says]: “Their sins and their lawless acts, I will remember no more.” 18 Now where [there is] forgiveness of these, no longer [is there] an offering concerning sin.
1 Cor. 6:17; 10:16–17.
1 Cor. 6:17 But the one being joined to the Lord is one spirit.
10:16–17 16 The cup of blessing that we bless, is [it] not a fellowship of the blood of Christ? The bread that we break, is [it] not a fellowship of the body of Christ? 17 Because [there is] one loaf, we the many are one body; for we all partake of the one loaf.
Acts 7:55–56; Heb. 1:3; 8:1.
Acts 7:55–56 55 But being full of the Holy Spirit, having looked intently into heaven, he saw the glory of God and Jesus standing at the right hand of God, 56 and he said, “Behold, I see the heavens having been opened and the Son of Man standing at the right hand of God.”
Heb. 1:3 who, being the radiance of [His] glory and the exact imprint of His substance and bearing all things by the word of power—through His having made purification of sins—sat down at the right hand of the Majesty on high,
8:1 Now the main point of the things being said: We have such a high priest, who sat down at the right hand of the throne of the Majesty in the heavens,
Matt. 6:20–21; John 4:21–24; Phil. 3:20; Col. 3:1–3.
Matt. 6:20–21 20 But treasure up for yourselves treasures in heaven, where neither moth nor rust disfigure, and where thieves do not break in, nor do they steal. 21 For where your treasure is, there will be also your heart.
John 4:21–24 21 Jesus says to her, “Believe Me, woman, that an hour is coming when neither on this mountain nor in Jerusalem will you⁺ worship the Father. 22 You⁺ worship what you⁺ do not know; we worship what we know, because salvation is of the Jews. 23 But an hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father also seeks such who worship Him. 24 God [is] Spirit, and it is necessary for those worshiping Him to worship in spirit and truth.”
Phil. 3:20 For our citizenship is in the heavens, from where also we eagerly await a Savior, the Lord Jesus Christ,
Col. 3:1–3 1 If, then, you⁺ were raised with Christ, seek the things above, where Christ is sitting at the right hand of God. 2 Mind the things above, not the things on the earth. 3 For you⁺ died, and your⁺ life has been hidden with Christ in God.
